Augmented Lagrangian method for imposing nonlinear multi freedom constraints in static analysis for frames using FEM
This paper focuses on the treatment of nonlinear multi freedom constraints using an augmented Lagrangian method in finite element analysis of frames. The process of imposing boundary constraints is developed by changing the assembly stiffness equation to produce a modified system of equation conside...
